The Illinois State Police, Secretary of State Police and more than 320 local law enforcement agencies are joining with the state Department of Transportation to crack down on drunk drivers. The campaign features the theme "Drive Sober or Get Pulled Over" and "Click It or Ticket" to encourage mandatory safety belt use.

Also participating are officials from the Illinois Department of Natural Resources, National Highway Traffic Safety Administration and Mothers Against Drunk Driving.

The effort is intended to reduce crashes on Illinois roads during a key summer travel time. Provisional IDOT data show 392 people have died in crashes through July 1 compared to 477 during the same time in 2013.
